I don't think the threat model justifies your solution. Locks on vehicles deter burglary of the vehicle's contents and theft of the vehicle itself. As long as automobiles have breakable glass, a lock will not prevent "smash-and-grabs". Ford has used simple code keypads on some of their cars for over 10 years. How will adding a strong cipher help prevent break-ins? Putting a strong cipher on the ignition would be a bit better. Many manufacturers use a special key that inlucdes a RFID or a specific resistor value to enable the ignition. However, this system can be bypassed by replacing the unit that reads the key with a previously stolen/modified unit. I believe preventing the control unit from being replaced would be the primary problem you would need to solve. -- Keith -----BEGIN PGP SIGNATURE----- iD8DBQE8zJ16kkhsfDhftukRAty0AJ9IXwFYJTe+u9GBvSWw15dJd/fFrgCeJUkv XP6YxTuz9FheZOcih7rEVQI= =l4PL -----END PGP SIGNATURE-----
